    <blockquote> <p>But I get an error "! [rejected]" and something about "non fast forward"</p> </blockquote> <p>That's because Git can't merge the changes from the branches into your current master. Let's say you've checked out branch <code>master</code>, and you want to merge in the remote branch <code>other-branch</code>. When you do this:</p> <pre><code>$ git pull origin other-branch </code></pre> <p>Git is basically doing this:</p> <pre><code>$ git fetch origin other-branch &amp;&amp; git merge other-branch </code></pre> <p>That is, a <code>pull</code> is just a <code>fetch</code> followed by a <code>merge</code>. However, when <code>pull</code>-ing, Git will <em>only</em> merge <code>other-branch</code> <em>if</em> it can perform a <em>fast-forward</em> merge. A <em>fast-forward</em> merge is a merge in which the head of the branch you are trying to merge into is a <em>direct descendent</em> of the head of the branch you want to merge. For example, if you have this history tree, then merging <code>other-branch</code> would result in a fast-forward merge:</p> <pre><code>O-O-O-O-O-O ^ ^ master other-branch </code></pre> <p>However, this would <em>not</em> be a fast-forward merge:</p> <pre><code> v master O-O-O \ \-O-O-O-O ^ other-branch </code></pre> <p>To solve your problem, first <em>fetch</em> the remote branch:</p> <pre><code>$ git fetch origin other-branch </code></pre> <p>Then merge it into your current branch (I'll assume that's <code>master</code>), and fix any merge conflicts:</p> <pre><code>$ git merge origin/other-branch # Fix merge conflicts, if they occur # Add merge conflict fixes $ git commit # And commit the merge! </code></pre>

    1. CONo, the problem is with fetching, not with merge step.

    2. CONormally, remotes are set up such that fetches are forced, even if they don't result in a fast-forward commit, so it shouldn't occur on fetch unless the OP changed something with the usual configuration. The fast-forward issue can occur during fetch *or* merge. What makes you say that the problem is definitely in fetching, and not in merging?

    3. COI follow these steps (fetch, merge). Git tells me there's nothing to do. When I try to commit, it falls over moaning about fast-forwards.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
